Chemistry of Life Processes Literature Review
Key Points and Main Concepts
- Metabolism: The chemical reactions that occur within living organisms to maintain life, including anabolism (building up) and catabolism (breaking down) of molecules.
- Enzymes: Protein molecules that act as catalysts, increasing the rate of chemical reactions in the body.
- Biomolecules: The fundamental building blocks of living organisms, including carbohydrates, lipids, proteins, and nucleic acids.
- Thermodynamics in Biology: The study of energy transformations in biological systems, including the laws of thermodynamics and their implications for life processes.
- Cellular Respiration and Photosynthesis: The two main processes by which organisms obtain energy, involving the breakdown of glucose (respiration) and the conversion of light energy into chemical energy (photosynthesis).
- Biochemistry of Disease: The study of the chemical basis of diseases, such as genetic disorders and cancer.
- Pharmacology: The study of drugs and other chemical agents used to treat diseases.
Conclusion
The chemistry of life processes is a vast and complex field that underpins our understanding of biology and medicine. This literature review has highlighted the key points and main concepts in this area, including metabolism, enzymes, biomolecules, thermodynamics, energy metabolism, and disease biochemistry.Experiment: Photosynthesis in Plants
Objective:
To demonstrate the process of photosynthesis in plants, specifically the production of oxygen by submerged aquatic plants in the presence of sunlight.
Materials:
- Aquatic plant (e.g., Elodea or Cabomba)
- Glass container (e.g., beaker or jar)
- Water
- Sodium bicarbonate (NaHCO3) solution
- Magnifying glass
- Light source (e.g., sunlight or lamp)
Procedure:
- Fill the glass container with water and add a small amount of sodium bicarbonate solution to provide carbon dioxide for photosynthesis.
- Place the aquatic plant in the container, ensuring that its leaves are submerged.
- Place the container in a well-lit area exposed to sunlight or under a lamp.
- Observe the plant for 1-2 hours, using the magnifying glass to examine the leaves closely.
- Look for the formation of small bubbles on the leaves of the plant.
Key Procedures:
Submerging the plant: Ensures that all parts of the plant are exposed to water and carbon dioxide.
Providing light: Light energy is necessary for the photosynthetic reactions to occur.
Observing bubble formation: The release of oxygen bubbles indicates that photosynthesis is taking place.
Significance:
This experiment demonstrates several key aspects of the chemistry of life processes:
- Photosynthesis: Plants use sunlight, water, and carbon dioxide to produce glucose (food) and release oxygen.
- Gas exchange: Plants exchange oxygen and carbon dioxide with the environment through their leaves.
- Importance of light: Light energy is essential for photosynthesis and the production of oxygen.
